10 all whom, it 71u14/ 5U/werft:

Beit known that we, CHARLES G. BUTTRICK and TIMOTHY B. FLANDnRs, both of Holyoke, in the county of Hampden' and State of Massa chusetts, have invented a new and1 useful Improvementin Spindle-Bolsters, of which the following is a specification and description.

The object of our invention is to provide a spindle-bolster within and vby which the spindle, when revolving, will be effectually and uniformly lubricated, 'and the application of the lubricant be maintained solong as the spindle is revolved, and by which the oil or lubricant is prevented from soiling the yarn or thread wound upon the bobbin,'and also to give to this bolster a yielding or self-adjusting bearing within its case; and we accomplish this by the mechanism substantially as hereinafter described,and illustrated in the accompanying drawings, in. which- FigureI is a plan view of a spindle-bolster and case made according to ourinveution,'the spindle being in section. Fig. II is a vertical section of the' same at lineA, with a spindle within the bolster in elevation. Fig. III is a plan view of the bolster-case. Fig. IV is a vertical section of the same at line B. Fig. V is a plan view of the bolster. Fig. VIis aside elevation of the same. Fig. vVII is a tra-nsverse section of the bolster, bolster-case, and spindle at line C of Fig. II, in which the spindle is in elevation. Fig. VIII is a transverse section of the same at line D of Fig. II. Fig. IX is a modification ofthe upper end of the bolster, and Fig. X is a plan view of another form of the same and within its case.

In the drawings, 2 represents the bolstercase, whose lower part, 7, is fixed in the rail of an ordinary spinning-frame, preferably by a set-screw, and above this part is a cup or oil-reservoir, 3, which ordinarily rests upon the rail, and we bore out the lower end of this case of a uniform size up to an internal shoulder, 12, and an internal screwthread is made in the lower end to receive the threaded end .of a nut, 9, provided with a shoulder, 17, on its upper end. Above this internal shoulder, 12, we bore out the case of somewhat smaller diameter, preferably up to a point .near its upper end, as at 16, above which we prefer to again reduce the bore in diameter, as shown in Fig. IV, and an oil-hole, 10, is made through the case at or near the bottom of the reservoir 3, as'shown clearly inFigs. II and IV.

lIhe bolster 4 we make, preferably, of uniform diameter throughout its length,with an external annular oil-cup, 5, near its lower end,with

a shoulder, 6, just below thisl cup, as shown in Fig.VI,and we make a spiral groove, 13, along the inside of this bolster, and extending, preferably, from its lower end to a point little below its upper end, as shown in dotted lines in Figs. II and VI, and with this form of case we make any desired number of grooves, 1 5, in the outside of this bolster, near its upper end,with any desired number of holes, 14, madethrough the-bolster, near its upper end, and communieating with one or more ofthe said grooves. We insert the bolster 4c into its case from the lower end of the latter until the upper side of the cup 5 `impinges against the internal shoulder of the case, andwe then insert a spiral or helical spring, 8, within the lower end of the case and around the outside of the bolster, below the c'up 5; and `then turn the nut 9 into place in the lower end of the case, the upper end of the nut forcing the spring up against the lower side of the cup 5; and when thus in place the spring has a bearing at its upper end against said cup, and at its lower end against the upper end of the nut 9, and the bolster, as thus secured in the case, is free to turn in one direction; but the extreme upper end of the spring impinges, in a lateral or horizontal direction, against the shoulder 6 on the bolster, and the lower end of the spring impinges, in the Vopposite direction, against the shoulder 17 on the upper end of the nut, and prevents the bolster from revolving in the opposite direction. When thus secured within the case, the upper end of the bolster 4 snugly ts the interior of the case at its extreme upper end, except in the grooves l5, and these grooves extend down to a point below the shoulder 16; but below the said shoulder the bolster does not snugly fit the interior of the case, and there. is a little space between the exterior surface of the bolster and the interior surface of theV case, nearly the wholelength, to permit the lubricating-oil to flow down freely ICO e essen into the cup 5. Vhen the spindle is to be used, the lubricating-oil is put into the reservoir 3 of the case, and it iiows through the hole into the cup 5, and thence through the oil-aperture 1S in t-he bolster into the interior of the latter, and as the spindle snugly fits the interior of the bolster, but so as to revolve freely therein, the oil is carried up in the spiral groove 13 bythe rotary motion of the spindle, and is forced up at the upper end of the bolster, so as to flow out through the orifices 14,whence it runs down the grooves 15, continues down in the space between the bolster and its case and flows into the cup 5, where it collects and again iiows through the oil aperture in the bolster and is again carried up the spiral groove, as before. In this manner a constant circulation of the lubricant is maintained, being constantly carried from the cup 5 up the spiral groove by the rotary movement of the spindle, and flowing out through the orifices 14 down and between the bolster and its case into the cup again, and thismovement of the lubricant continues so long as the spindle continues to revolve.

Instead of making the holes 1-1 in the upper end of the bolster, the grooves 15 might be carried up to the extreme end of the bolster, and as the oil is forced up it would iiow over into and down said grooves into the space between the bolster and its ease, and the circulation be maintained as before; or the bolv ster might be made of the same diameter throughout, and the upper end squared or made approximately prismatic, with slightlyrounded corners, as shown in Fig. X, so that the oil could 11ow down the space between each iiat side and the interior of the ease, and the circulation be maintained as before; but by making the holes 14 we are enabled to malte the extreme upper end of the bolster to closely lit the inside ot' the case with no inequalities in the upper end of the bolster, into which dirt and grit would fall, and yet to cause the oil to pass so close to the upper end of the bolster as to lubricate the latter the entire length of the bearing of the spindle; another modification ofthis construction being shown in Fig. IX.

\Ve are aware that a bolster lias heretofore been made in which a spiral groove was made along its length inside,to cause the oil to flow up; but as there was no separate ease for the bolster, the oil would collect and flow down the outside, and as the bobbin, when placed on the spindle, extended down around the bolster, the oil would be liable to get into contact with the thread on the bobbin, especially it' the latter were cracked or split, as many of the bobbins often are, and large quantities of thread was thereby spoiled. Our invention entirely obviates this objection, as we provide means to carry the oil down again tothe oilcnp, where it is again used, and the outside of the bolster-ease is always perfectly free 6 5 from oil from the spindle or its bearings.

Inasniueh as many of the spindle-holsters have a firm or solid bearing, it is evident that the bolster may be driven or otherwise secured fast within the bolster-ease, instead of 7o being secured by the spring, so as to have a yielding bearing, and yet be operative as to the feature of maintaining a constant circulalation of the lubricating-oil entirely inside the bolster-ease; but inasmuch as the bearing of the spindle within the bolster is quite long, we deem it especially desirable to have the upper end of the bolster fill "the ease to have a bearing therein, and combine the feature of the yielding bearing with the mechanism for maintaining the circulation of the oil upon the bearing. 0f course, as the spindle revolves during the operation of spinning, the bolsterease, being fixed in the rail, remains stationary, and the bolster is held stationary therewith by the abutting of the ends of the spring against the shoulders 6 and 17; and if it should be desirable to revolve the spindle in the opposite direction for any purpose a spring wound in the opposite direction should be used.

Having described our invention, what we claim as new is- 1. The combination of a bolster spirally grooved inside and provided with an oil-cup y near its lower end, and with apertures made 95 through said bolster, communieati ng with said cup, with a. bolster-case provided with an oilreservoir and an oil-aperture therefrom to the inside of the ease, and with au oil-space between the inside of the case and the outside 10o of the bolster, and into which casethe bolster is adapted to be secured and held stationary, substantially as described.

2. The combination ol" a bolster spirally grooved inside and provided with an oil-cup, 105 5, and a shoulder, 6, with a bolster-case provided with an oil-reservoir and an oil-aperture therefrom to the inside of said ease, and with an oil-space between the inside of the ease and the outside of said bolster, annt pro I IO vided with a shoulder at its upper end, and secured in the lower end of said case, and a helical spring encircling the lower end of said bolster, and extending from said nut to the shoulder or cup of said bolster, substantially 115 as described.
